In contrast to the city council’s generosity, up to a quarter of local authorities have refused to take part in the national voluntary scheme complaining about the costs of taking children and young adults into their care.

Booo! Hissss! How uncharitable! Not like saintly Brighton!

City councillors are calling for more resources from Westminster to help the authority meet its commitments.

Westminster doesn't have any 'resources'. It's taxpayer pockets they'll be rummaging around in. As usual.
